This document covers the following topics:
The utility SYSEXT provides the following new
application programming interfaces (APIs):
| API | Description |
|---|---|
USR4215N |
Return a list of resources (short object and long resource name) of a Natural library according to the forwarded range parameters. |
Natural for Ajax is now delivered in the Version 1.2.4. It is based on Application Designer Version 8.0.
Support is provided for the following:
Certain controls can be bound to Natural control variables so that
the modification status of a Natural operand that represents the value of the
control can be checked with IF
control-variable MODIFIED. See
XCIDATADEF - Data
Definition in the Natural for Ajax
documentation.
The Natural system variable
*CURS-FIELD can be used
in Natural for Ajax applications to identify the operand that represents the
value of the control that has the input focus. When the Natural system function
POS
is applied to a Natural operand that represents the value of a control, it
yields the identifier of that operand. See also
Natural
Parameters and System Variables in the Natural
for Ajax documentation.
The statusprop property for input
controls such as FIELD has been split into two separate properties:
statusprop and
displayprop. See
Dynamically Controlling the Visibility and the Display
Status of Controls in the Natural for
Ajax documentation.
It is now possible to define a Natural for Ajax application as a servlet in the file web.xml. This makes the definition of security constraints for individual applications easier. See Wrapping a Natural for Ajax Application as a Servlet in Configuring the Client which is part of the Natural Web I/O Interface documentation.
The following new features apply only to Natural maps, not to rich GUI pages:
With the configuration tool, it is now possible to configure the behavior of a double-click. The double-click can be assigned to a function key or can be disabled. See Overview of Session Options in Configuring the Client which is part of the Natural Web I/O Interface documentation.
With the configuration tool, it is now possible to define that all function keys are to be shown, including those which do not have names. This makes sure that the function keys are always displayed at the same position. See Overview of Session Options in Configuring the Client which is part of the Natural Web I/O Interface documentation.
The Natural Web I/O Interface is now delivered in the Version 1.3.5.
Support is provided for the following:
It is now possible to define different styles for output fields which are based on variables and output fields which are based on literals (J2EE only). See Defining Different Styles for Output Fields in Configuring the Client which is part of the Natural Web I/O Interface documentation.
Processing rules (inline rules and Predict free rules) are now supported in Natural adapters in the same way as in Natural maps.
A field in a PROCESS PAGE statement can now be
associated with a control variable. When the value returned for that field is
not equal to the value sent, the field is regarded as modified and the control
variable is set to modified.
The compiler option PCHECK has been enhanced for
use in conjunction with objects of type adapter. With
PCHECK set to ON, the
PROCESS PAGE USING statement now checks
the parameter number, format, length and array index boundaries not only at
execution time, but already at compile time.
In addition, the parameter check at compile time has been expanded to
other invoking statements, such as
PERFORM (external subroutine),
INPUT USING
MAP, and to the calling of
helproutines.
The precision of the result field in an exponentiation with an exponent of format numeric (N) or packed (P) has changed in Natural Version 6.3.7 in order to achieve a result which is more precise.
In case of an exponentiation where the exponent is a numeric or packed
operand with one or more digits after the decimal point (for example,
N1.1 or P1.1), a result field of format float (F8)
instead of format packed (P) is now generated.
The change is effective after a RUN,
CATALOG or STOW in
Natural Version 6.3.7. An EXECUTE of programs which
are compiled under a previous version (Natural Version 6.3.6 or below) has no
effect.
Example:
DEFINE DATA LOCAL 1 #F8 (F8) END-DEFINE COMPUTE ROUNDED #F8 = 1 + 5 ** 0.5 /* The result field of the exponentiation 5 ** 0.5 is now F8 instead of P15.0 PRINT #F8 /* After CATALOG, the result in Natural Version 6.3.7 is +3.236067977499789E+00 /* Result in Natural Version 6.3.6 is +3.000000000000000E+00 END
The documentation has been adapted accordingly. See Performance Considerations for Mixed Format Expressions in the Programming Guide.
With Natural Version 6.3.7, the new DDM EMPLOYEES-V2009 is
delivered. This DDM is used by the new sample programs supplied with the
SYSEXV utility. This DDM makes use of
new Adabas data types introduced with Adabas Version 6. The respective
EMPLOYEES data requires Adabas Version 6.1.6 or higher.
The following application programming interfaces (API) in the library
SYSEXT have been enhanced:
USR0330NThe complete timestamp value for Natural objects is now returned.
USR0360N, USR0421N and
USR1020NA new optional parameter named LAYOUT-CHECK
is available. The layout definition is checked when a value other than blank is
specified for this parameter. Error messages that do not fit into the ranges
are not processed.
Natural Remote Procedure Call (RPC) is available as a separate subcomponent of Natural. It has its own version number. This measure takes into account that Natural RPC is a cross-platform component and makes it possible to provide new Natural RPC versions independent of new Natural versions for the various platforms supported.
With Natural Version 6.3.7, an enhanced Natural Remote Procedure Call Version 6.3.3.1 is delivered that replaces the existing Natural RPC Version 6.3.3.
As of Version 6.3 of Natural Remote Procedure Call (RPC), the following changes and enhancements are available:
The system command RPCERR has been enhanced
to show the full error message text returned by an EntireX RPC server.
The following enhancements have been applied to the user application
programming interface
RPCINFO and the parameter data area
RPCINFOL:
RPCINFO has been enhanced to retrieve the error message
text returned by an EntireX RPC server.
The fields S-NODE, S-NAME,
C-NODE, C-NAME have been enlarged from A8 to A32 to
be more compliant with EntireX.
RPCINFO is loaded to the library SYSTEM on
system file FNAT and is immediately available to all user
applications.
All enhancements are compatible with existing applications.
Notes:
RPCINFOL, you may be concerned if the enlarged fields are
displayed. Either adapt your output layout accordingly or add the session
parameter AL=8 where appropriate.
RPCINFO from the FUSER system file.
The
Stub Generation function of the
SYSRPC utility has been enhanced by the direct command
COMPAT IDL in order to optionally generate stub
subprograms that are more compliant with EntireX RPC servers and the reliable
RPC. If COMPAT IDL is specified and an EntireX RPC
server is called by a Natural client, the parameter definitions on the
Stub Generation screen must correspond to the IDL
definition for the EntireX RPC server.
With the next version of Natural, COMPAT IDL
will be the default. For compatibilty reasons, an option will be provided to
generate stub subprograms as in previous Natural versions.
Please note that the term "stub subprogram", which in earlier versions of EntireX was also used to refer to application-dependent, Workbench-generated pieces of code for issuing and receiving remote procedure calls, will no longer be used. In the EntireX documentation, these objects are now referred to as "interface objects". In the Natural Remote Procedure Call documentation, however, the term "stub subprogram" is still prevailing. It will be replaced in one of the next versions of Natural RPC.
The following enhancements are provided with Natural Security Version 6.3.7:
The following enhancements are provided for users:
The function Copy User has been enhanced: You can enter the name of the new user not only in the new profile but already in the window which is displayed when you invoke the Copy function. This name is then written into the new profile (where you can still change it, of course).
A new user exit,
NSCUSEX2, is provided in the library
SYSSEC. It allows you to review the changes you have made to a
list of group members. It is invoked when you use the user-maintenance function
Edit Group Members and
CATALOG the changes to the group. It displays a list
of the group's members, indicating which members have been added to the group
and which have been removed from it.
The following enhancements are provided for libraries:
The function Copy Library has been enhanced: You can enter the name of the new library not only in the new profile but already in the window which is displayed when you invoke the Copy function. This name is then written into the new profile (where you can still change it, of course).
UNIX shell commands can be executed from within a Natural program by
invoking the Natural user exit SHCMD via the statement CALL
SHCMD. With Natural Security you can now control for each library the
execution of UNIX shell commands from within Natural programs by
allowing/disallowing the execution of the CALL SHCMD statement in
the Command Restrictions section of
library profiles.
The following enhancements are provided for utilities:
In the security profiles for the
SYSERR utility, you can now control the
use of SYSERR direct commands. You can allow or disallow each
command for all users, or allow it for Natural Security administrators
only.
The session option
Utilities option in the default
profiles of utilities SYSMAIN and SYSOBJH has been
enhanced: In addition to the existing values Y and N,
you can specify the new value O: This is identical to
Y, but has the following additional effect:
If you use SYSMAIN or SYSOBJH to process the
contents of a library in whose library profile the general option
Utilities is set to O (= processing permitted
for owners), and you as an owner require a countersignature, the
countersignature prompt will be suppressed; instead, the library will be
excluded from SYSMAIN/SYSOBJH processing.
This enhancement is only relevant online, because in batch mode countersignatures cannot be processed anyhow.
The following application programming interfaces (APIs) have been enhanced:
The API
NSCADM has been enhanced. It allows you
to compare a preset value (as set in the
Library and User Preset Values)
with the the corresponding actual value in user profiles, and provides a list
of all user profiles in which the value differs from the preset value. For
details, see example program PGMADM04 and text member
TXTADM04 in the library SYSSEC.
The API
NSCXR has been enhanced. It allows you
to retrieve information about the access rights to an individual module in a
library, for all users who have access to the library. For details, see example
program PGMXR018 and text member TXTXR018 in the
library SYSSEC.
The following other enhancements are provided:
If a startup transaction is specified in a Natural Security library profile, it will be executed after a successful logon to the library. In a Natural Development Server environment, however, when a library is selected from the tree view in the mapped environment, the execution of a startup transaction may not be desired. A new Administrator Services option NDV Startup Inactive, which can be set in the Library And User Preset Values, allows you to suppress the execution of startup transactions in a mapped environment.
The function Copy Mailbox has been enhanced: You can enter the name of the new mailbox not only in the new profile but already in the window which is displayed when you invoke the Copy function. This name is then written into the new profile (where you can still change it, of course).
This section provides additional information that you should be aware of after having installed Natural.
The following information applies when using Entire Connection Version 4.5.2 or above.
A different error message is now issued when the user cancels a file
transfer that has been started with the Natural statement DOWNLOAD PC
FILE or UPLOAD PC FILE. As of Natural Version 6.3.7, the
error message NAT1016 is issued.
Up to Natural Version 6.3.6, one of the following error messages was issued: NAT1500, NAT6220, NAT6221.
This change may affect existing Natural applications which handle the
error situation inside an ON ERROR statement.
The execution of the Natural installation on an older X server (for example, eXcursion) may cause problems with the user interface (character set etc.).
